Improvement in syringes



UNITED STATES PATENT OFFICE.

AND O. B. LEAVENWORTH, OF SAME PLACE.

IMPROVEMENT IN SYPLINGES.

Specification forming part of Letters Patent No. 47,245, dated April 11, 1865.

To all whom it may concern: Be it known that I, LUKE WnEELooK, of New Haven, in the county of New Haven and State of Connecticut, have invented a new andnsei'ul Improvement in Syringes; and I do hereby declare the following to be a full, clear, end exact description of the same, when taken in connection with the accompanying drawings and the letters of reference marked thereon, and which said drawings constitute part of this specification and represent, in-

Figure l, a side' view; Fig. 2, a longitudinal central section; Fig. 3, the discharge-pipe enlarged, and in Fig. 4 the discharge end of a female-syringe.

My improvement relates more particularly to Venereal syringes, butthe same principle may be applied in the construction of other syringes.

My invention consists in forming the disA charge-apertures inclined outward instead of inward, as in common syringes.

To enable others skilled in the art to construct and use my invention, I will proceed being a single aperture, as in ordinary malesyringes. I make several, as seen at a a, Fig. 3, inclined so as to discharge back, as denoted by arrows, the object of this being to discharge the contents ot' the syringe back rin ges neither do I claim piercin g the enlarged end of syringes with numerous small holes, as in the patent of Ira Warren, December 6, 1853, in which none of the holes open toward the syringe. i

What I claim as new and useful, and desire to secure by Letters Patent, is-

A syringe when the discharge-apertures are formed substantially as and for the pnrpose specified. i
